The Edit Data Area 2 command allows you to key over the existing data
in a character data area. The edit display appears in the same
format as used by DSPDTAARA. Each line of 50 bytes is a separate
field.
Thus you can key (or key over) formatted lines with EDTDTAARA2. This
allows for the values to be easily seen with DSPDTAARA.
The EDTDTAARA tool also allows editing, but treats the entire
contents as a single field on the display.
The EDTDTAARA3 allows editing in Hex.
A typical command would be:
EDTDTAARA2 DTAARA(xxxx)
When the display appears, 9 lines (450 bytes) are displayed. If the
data area size is greater than 450 bytes, rollup is allowed to access
each succeeding 450 bytes. Rolldown is valid to re-display prior
screens.
When the user presses Enter, a check is made to ensure that data has
not been keyed beyond the actual length of the data area. An error
message will be displayed if this occurs.
If data below X'40' exists, it is changed to blank and and error
message will appear.
Contrast with other functions
-----------------------------
The system CHGDTAARA command does not allow you to key over the
existing value. You can change the data, but the existing value is
not displayed.
The TAA Tool command EDTDTAARA allows you to key over the existing
value, but considers the entire data area as a single field (if the
data area is less than 800 bytes in length). EDTDTAARA can be used
to edit decimal data areas.
Depending on what use you are making of the data area, either
EDTDTAARA or EDTDTAARA2 should meet your editing needs.
Command parameters *CMD
------------------
DTAARA The qualified file name of the data area. The
library value defaults to *LIBL. *CURLIB may be
specified.
Restrictions
------------
Only character data areas may be edited. For numeric data areas, use
EDTDTAARA.
If characters below X'40' exist, a prompt for the EDTDTAARA3 command
occurs.
If the TAALICENSE data area in TAATOOL, TAAINS, TAAINS2, or TAAINSLIC
is specified, no changes can occur to positions 1901 - 2000.
